How do you map the ocean floor? Who created the first map of the bottom of the sea?

Cartographers were putting the depths of the ocean on the map long before Google Street View provided their very first underwater panoramic images of the Great Barrier Reef, and the Apple map app shipwreck. The book, Soundings: The Story of the Remarkable Woman Who Mapped the Ocean Floor, by Hali Felt, tells the story. If you are interested in exploring the history of women in science, and the changes in scientific thought over the last century, then this book is worthy of your time.

I love carto history, never knew about this piece of it.

Does anyone have any insight as to what this means?:

“[The lakes] should not be solid blue or green or edged in green. If they do turn out any of the above ways I think the best thing would be to call up Mr. Heintz and have his boy paint out the color overlay & print the damn lakes in yellow.”

Was there a printing press limitation or what influences this choice in design?

I see a lot of maps made showing water features a shade of blue. This make the colours associative.
